The movement of water that has the greatest effect on the growth of producers is <em><u>upwelling</u></em><em><u /></em>.
Upwelling is a rising of a liquid. The reason upwelling is much better for producers is because it is a slow rising in the water level, preventing erosion to the topsoil and still giving the necessary amount of water and nutrients the producers need.
Thank you for your question! I hope this helped! Have an amazing day and feel free to let me know if you need any more help with anything :D <span />
Answer:

Explanation:
m = Mass attached to spring = 14 kg
g = Acceleration due to gravity = 
x = Displacement of spring = 
k = Spring constant
The force balance of the system is given by

The spring constant for that spring is
.
It will be unstable system because it will not be able to recover from the disturbance

Explanation:First, we’re going to assume that the top of the circular plate surface is 2 meters under the water. Next, we will set up the axis system so that the origin of the axis system is at the center of the plate.
Finally, we will again split up the plate into n horizontal strips each of width Δy and we’ll choose a point y∗ from each strip. Attached to this is a sketch of the set up.
The water’s surface is shown at the top of the sketch. Below the water’s surface is the circular plate and a standard xy-axis system is superimposed on the circle with the center of the circle at the origin of the axis system. It is shown that the distance from the water’s surface and the top of the plate is 6 meters and the distance from the water’s surface to the x-axis (and hence the center of the plate) is 8 meters.
The depth below the water surface of each strip is,
di = 8 − yi
and that in turn gives us the pressure on the strip,
Pi =ρgdi = 9810 (8−yi)
The area of each strip is,
Ai = 2√4− (yi) 2Δy
The hydrostatic force on each strip is,
Fi = Pi Ai=9810 (8−yi) (2) √4−(yi)² Δy
The total force on the plate is found on the attached image.
